IMPROVEMENT IN CANISTERS.

Specification forming part of Letters Patent No. 159,538, dated February 9, 1875; application filed April 29, 1874.

To all whom it may concern:

Be it known that we, THEODORE W. BUR- GER and JACOB A. GRAFF, both of New York, in the county and State of New York, have jointly invented certain Improvements in Canisters, of which the following is a specification:

Our invention relates to certain improvements designed more especially for application to canisters for'holding tea, coffee, and spices, for the purpose of ornamenting said canisters, and giving them a handsome appearance when exposed in a store containing the articles for sale.

The invention consists in the combination, in a canister, of one or more guards with one or more mirrors, secured in position upon the canister in' front of the guard or guards, in such a mannerthat the mirrors are protected against any outward pressure by the contents within the vessel.

In the accompanying drawing, Figure 1 is a front view of a canister embodying my improvements. Fig. 2 is a vertical section of the canister looking toward the front. Fig. 3 is a horizontalsection. Fig. 4 is a vertical section, taken in the line w x of Fig. 3.

The canisterA may be constructed of metal or other suitable material, and is made preferably with its front forming three faces, a a as, or three sides of a hexagon, the remaining portion of the canister being of square or approximate form in its horizontal section.

To one or more of the faces is attached a mirror, B, which may be of angular, elliptical, or other desirable form, and may be of glass or of polished metal, as desired. The mirror is placed with its back against the metal of the canister, and is secured in place by a bead, c, which may be attached to the canister by soldering or.riveting, or in any other suitable manner, and may be of any suitable material.

When the canister is made of metal the bead is likewise made of metal, and is secured by soldering, or by means of tongues on the beads passing through slits in the canister, and turned down on the inner side, in which latter case the bead may be readily removed,

when desired, to remove and replace the mirror.

In order to protect the mirror from the effects of pressure of the contents of the canister toward the outside a guard is pr0- vided, consisting of a plate, D, attached to the inside of the canister opposite to the mirror, said plate being of concavo-convex form, and arranged with its convex surface toward the center of the canister. This plate does not reach entirely to the top or bottom of the canister, so that it need not diminish the carrying capacity, as a portion of the contents may enter between the plate and the front of the canister. The plate is secured in place by slipping its edges under grooved strips 0 attached to the canister, so that it may be readily removed, when desired.

It will be seen that the mirrors are attached to the canister in a difierent manner from that usually practiced, inasmuch as they are placed with their backs directly against the material of which the canister is composed, which material remains intact; whereas in the ordinary mode of attaching mirrors they are inserted from the rear through an opening made for the purpose, and are thus more exposed to danger of breakage from the rear.

From the foregoing it will be understood that we do not broadly claim providing a canister with a mirror, as such of itself is old and well known. 4

What we claim as new, and desire to secure by Letters Patent, is-

A tea-canister, provided on the interior with the concavoconvex guards D, fitted under flanges e, in combination with the mirrors B, placed directly upon the canister-body, and secured thereon by the surrounding heads 0, as herein shown and described, for the purpose specified.
